George and Ryan had a total of 170 stamps at first. After George bought 20 more stamps and Ryan gave away 14 stamps, George now has the same number of stamps as Ryan. How many stamps did George have at first?
|
George |
Ryan |
Total |
Before |
1 u - 20 |
1 u + 14 |
170 |
Change |
+ 20 |
- 14 |
|
After |
1 u |
1 u |
176 |
Total number of stamps in the end
= 170 + 20 - 14
= 176
2 u = 176
1 u = 176 ÷ 2 = 88
Number of stamps that George had in the end
= 1 u
= 88
Number of stamps that George had at first
= 88 - 20
= 68
Answer(s): 68
